^IINCE the first immigrant landed, axe in hand, and built 
^ himself a timber stockade against arrow and tomahawk, 
America's mighty forests have been bulwarks of defense. 
Nor have they failed to answer the bugle today! Behind the 
American Eagle stand the forests . . . rank upon rank, 
staunch, proven, and deep. 

America's forests have been from the beginning America's 
original and still most abundant natural resource. In peace, 
they build our homes, our schools, our churches, and our fac- 
tories. In war, they build barracks, ships, munition plants, and 
perform an infinite variety of services, dramatic and unsung. 

When America awoke to this emergency, lumber was ready, 
willing, and able to play a major role . . . immediately! No 
"retooling" ... no "plant expansion" ... no "bottlenecks"! 
Lumber housed the troops . . . "The Greatest Carpentry Job 
in History" ... in jig time. Lumber is building shipyards 
and ships, aircraft factories and 'planes, ordnance plants and 
shell boxes, and . . . through the development of improved 
engineering methods ... is performing many tasks formerly 
thought possible only by materials urgently needed for actual 
fighting tools. Thus, intelligent application of lumber as an 
engineering material has released and is releasing many mil- 
lion tons of "bottleneck" materials to the fighting forces. 

Since the birth of the nation, American forests have yielded, 
in war and peace, some 2,200,000,000,000 board feet of lum- 
ber. Standing today are growing forests with almost as much. 
Under planned management these forests assure even greater 
supplies for the future. 

More than a million men are trained to work in wood, a 
labor reservoir exceeding all other crafts. Lumber is the 
most easily worked, most economical, most readily obtainable 
structural material.

springs first to mind, naturally, 
when one thinks about wood's service 
to the Navy and, make no mistake 
about it, wood ships are still an im- 
portant arm of the service. Along the 
New England coast craftsmen sons of 
generations of Yankee shipbuilders 
lire turning out wood cargo vessels, 
trawlers, mine layers, patrol boats, as 
fast as ever they can. On the Lakes 
and along the Gulf swarms of hum* 
ming mosquito boats are hatching. 
Even metallic monsters like the U. S* S. 
North Carolina, seen here firing the 
mightiest broadside in naval history, 
need wood for their decks. As evi- 
denced in the following pages, wood

After three hundred years, forests cover 
one-third the United States. Continuous 
harvests from these forests supply all 
needed lumber for defense demand-, 
home uses, and foreign trade.

J.V the mass re-adjustments of population necessi- 
tated by the mushroom growth of defense indus- 
tries in many localities and other emergency activities, 
housing has been a critical problem • • . housing 
for extra thousands of workers hastily recruited by 
defense plants • . . housing for the home folks 
evacuated from land needed for maneuvers. Here, 
again, lumber has "come through in the pinch". 
Wood houses, many completely prefabricated and 
erected at phenomenal speed, have gone up where 
and as needed without delay and at minimum cost.

SHORTAGE of steel among 
^ the Central Powers during 
and immediately after World 
War I resulted in the inven- 
tion of a system by which an 
older structural material . • . 
lumber . . . can do the kind 
of ivork previously expected 
only of steel. Now an enter* 
gency development of an old 
war seems to fit peculiarly well 
the widespread structural de- 
mands of preparations against 
a possible new one. America's 
abundance of timber, plus new 
commercial fabrication facili- 
ties developed since the inau- 
guration of timber connector 
engineering, has facilitated 
rapid and economical produc- 
tion of all types of defense

is the ideal "substitute" for many critic(d list mate-
